近年来,我国棉花育种工作取得了很大的成就,如徐州1818、徐州142、鲁棉一号、洞庭一号等自育品种产量均高于引进品种,但有些品种在纤维品质尤其是纤维强度方而尚有差距,不能完全满足纺纱要求。因此,我们从1973年起开展了以改进陆地棉纤维强度为重点的品质育种工作。关于提高陆地棉纤维强度的育种,国外已进行了数十年,主要有两种途径:一是与野生
In recent years, great achievements have been made in cotton breeding in our country. For example, the yield of self-breeding varieties such as Xuzhou1818, Xuzhou142, Lumi Mian1 and Dongting-1 is higher than that of imported varieties, but some varieties have higher fiber quality, especially fiber strength There is still a gap between the parties, can not fully meet the spinning requirements. Therefore, since 1973, we conducted quality breeding work focused on improving the fiber strength of upland cotton. Breeding to improve the strength of upland cotton fiber, abroad has been carried out for decades, there are two main ways: First, and wild
